An MP has told ITV Central that at least one of the three civil servants who were suspended over the West Coast trains bid also worked on the bid which Derby train maker Bombardier lost.
It went to Siemens instead.
That bid process has been pulled after the secretary of State, Patrick Mcloughlin found "completely unacceptable mistakes" made by civil servants - leading to three of them being suspended.
A rail magazine has reported that two of the three people suspended also worked on the Bombardier bid.
It didn't anwer that question specifically but instead said:
"The team involved in the analysis and evaluation of the Inter City West Coast procurement was a different team from that involved in the analysis and evaluation of the Thameslink rolling stock bid."
But a Derby MP says at least one of the suspended civil servants was involved in the Bombardier deal.
"I've had a letter from the minister himself confirming that at least one of the civil servants was part of the same process, so this whole issue relating to the Thameslink contract is getting murkier and murkier and I do think it's about time the government actually looked at this whole decision that hey've taken so far and look at the tendering process again to give Bombardier a chance to ge this work which is vital for Derby and vital for the UK economy."
Four other MPs wrote to the secretary of state saying they didn't want to the mistakes made by the civil servants in the West Coast bid to have been repeated in the Bombardier Thameslink bid.
But tonight there's no sign of a rethink from the department which told us they expcet to sign contracts with Siemens in the New year.
